Cloud Computing HW 1

Link to the application repository which is being used: Botnak repo

Description

I use junit tests to test the above mentioned application. Then, I use gradle and sbt to build and run those tests. The gradle and sbt automate the process of managing dependencies. In junit tests I test the utilities that the application uses to perform it's core functionality. The limitations of the implementation are that it only checks a very precise scope of the application. As only unit testing can be performed using junit, it does not help in black box testing and only covers some scope in white box testing.

Requirements

You will need the latest version of Java 8 to run tests. Download it here.

You will also require intellij ide. Download it here.

Junit and other dependencies will be automatically added using gradle and sbt.

How to run the project

1. Copy the repo clone "https://[email protected]/sankul/sankul_rawat_hw1.git".
2. Open intelliJ.
3. In intellij, open project using version control -> git.
4. Follow on screen instructions to clone and import project.
5. Once the project is open, open terminal window inside intellij.
6. To run using gradle, execute following command gradle build in terminal, this will build the project and run tests.
7. To run the tests again execute gradle clean test in terminal again.
8. To run using sbt, execute following command sbt clean compile test in terminal, this will compile and run the tests.

Location of tests

1. The junit tests are present on path sankul_Rawat_hw1/src/test/java/ .
2. build.gradle and build.sbt files are present in the root directory of the project.

Testing of application

Following monitoring tools were used to test the application Tools list

###JConsole I use JConsole to monitor performance and resource consumption of java applications that are running.

###VisualVM I use VisualVM to profile the performance and resource consumption of the java application.

Screenshots of VisualVM output for this application:

###VisualGC I use VisualGC to collect and graphically display garbage collection, class loader, and HotSpot compiler performance data.

###jStack I use jstack to print Java stack traces of Java threads for a given Java process i.e. the application.

Screenshots of jStack output for this application:

###jcmd I use jcmd to send diagnostic command requests to the JVM, and diagnose JVM and Java Application.

Screenshots of jcmd output for this application:

###jmap I use jmap to print shared object memory maps or heap memory details of the application.

Screenshots of jmap output for this application:

###jps I use jps to report information on JVM.

Screenshots of jps output for this application:

###jstat I use jstat to display performance statistics for the JVM.
